| Jul 12, 2013 at 8:45 | comment | added | Alexandre Eremenko | Ofer, thanks. What is the reference on Barnard? I am still confident that what I wrote is true, but the details are somewhat technical, and it will take some time to write. | |

I wrote ``more examples'' because you can use e.g. the above mentioned results of Barnard to sweep out all zeros from the positive sector, and create thus new examples from a given one. I will review your answer below, it looks very promising. Thanks. | |

| Jul 8, 2013 at 12:15 | comment | added | Alexandre Eremenko | Ofer, can you be more specific on "many examples"? Do you have an example which contradicts the conjecture that Obrechkoff's condition is necessary and sufficient? | |
